When bogus memory access happens in mem[set,cpy,move]() it's usually
caller's fault.  So don't blame mem[set,cpy,move]() in bug report, blame
the caller instead.

Before:
  BUG: KASAN: out-of-bounds access in memset+0x23/0x40 at <address>
After:
  BUG: KASAN: out-of-bounds access in <memset_caller> at <address>
